It is the night before September first, the night before Remus must leave again to resume his teaching position at Hogwarts.
Tonks doesn't want him to go...

“I don’t want you to leave,”
Tonks said to him quietly.
Remus considered her fondly for a moment before speaking.
“I know you don’t, but I have a great job in the universe of occupations.”
He told her simply.

Cute, short-story that I wrote in like ten minutes.
*I don't own the poem!*
